The primary use of this program is to compare Gleason or Klingelnberg calculated tooth geometry against the ideal geometry. It is well known that neither Gleason nor Klingelnberg machines deliver ideal spiral bevel tooth form. (Exception is for parallel tooth geometry that has disadvantages of root undercut on the pinion toe.) 90% of gears cut on Gleason or Klingelnberg machines are not ideal from gear theory prospective. Ideal tooth form delivers the highest torque capacity with lowest transmission error while less sensitive to misalignments of the gear shafts. The ideal tooth geometry is calculated by our Excel Spiral Bevel program. You need both our programs: Spiral Bevel and Bevel+ in order to validate your Gleason/Klingelnberg nominal tooth data against the ideal gear tooth. Our Bevel+ Excel generates 3d model of your not ideal Gleason/Klingelnberg tooth form. Our Spiral Bevel Excel generates ideal 3d model of your gear tooth. Open both (your not ideal and our ideal) 3d models in CAD to see the difference. FEA can be done on both options since 3d models are available for standard FEA software. This is a low cost and easy to do method of an independent second opinion on the gear tooth design before transitioning into probable production issues. If significant differences are discovered either Gleason, Klingelnberg or we can recommend corrective engineering actions. We have a wide spectrum of mathematical gear geometry modeling and simulation tools to help with machine summary corrections to bring the tooth geometry as close to ideal as practical. ﻿

The 3d CAD models are also used for CNC machining of spiral bevel gears identical or better than gears cut by Gleason or Klingelnberg machines.

This program is very helpful for growing number of gear manufacturers who improve existing Gleason/Klingelnberg process with 5-axis CNC machining. CNC machining is used for rough cutting with following finish cut or grind on traditional generating machines. CNC machining is also used as a finish hard cut while rough cutting is done on Gleason or on Klingelnberg. Finish cut on a CNC provides several advantages compare to the traditional grinding methods. Also, finish CNC hard cut is used on gears previously impossible to grind, for example, aka Klingelnberg Cyclo Palloid.
